Who is this person that we may always trust ?
If you look at the flowers of the world, their varieties are beyond measure, and their beauty surpass expectations.
If you look at the living creatures in the sea, which include the numerous species of fish, you cannot but exclaim how wonderfully they have been created.
The insects, the birds, the trees, the stars, the animal, ...., all testify to the extreme wisdom of the Creator.
How may we know our Creator ?
Jesus : "I am the way, and the truth, and the life; no one comes to the Father, but by me." [John 14:6]
The only way to get to know our Creator is by obeying the teachings of Jesus (e.g. Sermon on the Mount), especially,
The above four are the most important things to do to know LORD, (my personal opinion only).
Firstly, we must be absolutely honest and upright. "Yes" be "Yes", and "No" be "No", under all circumstances. If one is not absolutely honest, one cannot make advances in physical sciences, natural sciences nor engineering. For example, a physicist would put forward a theory, and would carry out experiments to verify if experimental results correlate well with predictions from the theory. Very often the measured results turn out to be not what we expect, i.e. our theory is wrong, and we must be true to ourself, and admit that our theory is wrong. Then we may try other theory, and try still other theory, .... Then, perhaps, one day, we may arrive at the truth.
Secondly, we must have a kind heart, a heart full of love, and mercy. Because, when doing scientific/engineering research, very often, we are presented with several roads to proceed. Either we may proceed this way, or that way, or .... Which way shall we proceed? If we do not have a kind heart, but a different heart, say, a heart that delights in deep things, snobbish things, then, LORD will not guide us and we would usually take the wrong way, and waste tremendous lot of time and energy without arriving at any. Only a kind heart would resonate with that of LORD, and LORD would guide us to the correct way to proceed.
Thirdly, our heart must be pure, pure and humble, as that of a child. Because by then, the temptations and vanities of the world could not blind our eyes, and we be able to understand LORD better, step by step, day after day.
Fourthly, we must love LORD with all our heart, with all our mind and with all our soul, doing only that which is right in the sight of LORD. Also, we must love our neighbour. Jesus : "He who has my commandments and keeps them, he it is who loves me; and he who loves me will be loved by my Father, and I will love him and manifest myself to him." .. "If a man love me, he will keep my word, and my Father will love him, and we will come to him and make our home with him." [John 14:21-23]. Therefore "LOVE LORD = KEEP THE COMMANDMENTS OF LORD".
LORD is TRUTH. What is TRUTH ? The Pythagoras theorem you learn at school, will remain true even when there is no human. So are other theorems in Analytic Geometry, in Real or Complex Analysis (Maths), ... They are the same yesterday, today, and tomorrow. They remain true even if there is no human.
TRUTH governs every aspect of our life. If you throw an apple up, it will come down according to Law of Gravity. So is the trajectory of a space-ship that travels in space, it is still governed by Law of Gravity. Our every action/movement is governed by Mechanical Laws, and many phenomena are governed by Maxwell's Electromagnetic Laws. The working of your computer, the screen you are seeing now, are all governed by Electromagnetic Laws, and so they function. Who designed all those Laws? LORD did.
LORD, as TRUTH, is ever present. There is nothing that we do that can be hidden from His knowledge. Also there is nothing that we do are not fulfilled by Him.
If we are careful to do Jesus' teachings, then we will know that LORD's promises can be trusted,
LORD : " ... for I the LORD your GOD am a jealous GOD, visiting the iniquity of the fathers upon the children to the third and the fourth generation of those who hate me, but showing steadfast love to thousands of those who love me and keep my commandments. [Ex 20:5-6]
LORD : "If you will diligently hearken to the voice of the LORD your God, and do that which is right in his eyes, and give heed to his commandments and keep all his statutes, I will put none of the diseases upon you which I put upon the Egyptians; for I am the LORD, your healer." [Ex 15:26]
LORD to Joshua : " ... Only be strong and very courageous, being careful to do according to all the law which Moses my servant commanded you; turn not from it to the right hand or to the left, that you may have good success wherever you go. This book of the law shall not depart out of your mouth, but you shall meditate on it day and night, that you may be careful to do according to all that is written in it; for then you shall make your way prosperous, and then you shall have good success. Have I not commanded you? Be strong and of good courage; be not frightened, neither be dismayed; for the LORD your GOD is with you wherever you go." [Joshua 1:2-9]
Jesus : And do not fear those who kill the body but cannot kill the soul; rather fear him who can destroy both soul and body in hell. Are not two sparrows sold for a penny? And not one of them will fall to the ground without your Father's will. But even the hairs of your head are all numbered. Fear not, therefore; you are of more value than many sparrows. So every one who acknowledges me before men, I also will acknowledge before my Father who is in heaven; but whoever denies me before men, I also will deny before my Father who is in heaven. [Mt 10:28-33]
If you diligently obey the teachings of Jesus and of LORD, like that of brother David, who only did things right in the sight of LORD, you could sing like him,
David : "The LORD is my shepherd, I shall not want; he makes me lie down in green pastures. He leads me beside still waters; he restores my soul. He leads me in paths of righteousness for his name's sake.
Even though I walk through the valley of the shadow of death, I fear no evil; for thou art with me; thy rod and they staff, they comfort me.
Thou preparest a table before me in the presence of my enemies; thou anointest my head with oil, my cup overflows. Surely goodness and mercy shall follow me all the days of my life; and I shall dwell in the house of the LORD for ever."
On the other hand, if you put your trust in men, say, in Kings, or those in authority in the Secret Alliance, then
LORD : "Cursed is the man who trusts in man and makes flesh his arm, whose heart turns away from the LORD. He is like a shrub in the desert, and shall not see any good come. He shall dwell in the parched places of the wilderness, in an uninhabited salt land.
Blessed is the man who trusts in the LORD, whose trust is the LORD. He is like a tree planted by water, that sends out its roots by the stream, and does not fear when heat comes, for its leaves remain green, and is not anxious in the year of drought, for it does not cease to bear fruit.
The heart is deceitful above all things, and desperately corrupt; who can understand it? I the LORD search the mind and try the heart, to give to every man according to his ways, according to the fruit of his doings." [Jer 17:5-10]
Jesus : "Every one then who hears these words of mine and does them will be like a wise man who built his house upon the rock; and the rain fell, and the floods came, and the winds blew and beat upon that house, but it did not fall, because it had been founded on the rock. And every one who hears these words of mine and does not do them will be like a foolish man who built his house upon the sand; and the rain fell, and the floods came, and the winds blew and beat against that house, and it fell; and great was the fall of it."
