Often, in our flesh, when we are being tested by time we feel like God is not fulfilling the word He gave us, because its a test of our patience and trust. This world has trained us to want everything instantly, but somtimes God chooses for us to wait on Him. Its a time of submitting to God's timing and ways.
The purpose of the time test is for us to grow in faith, purify our motives and attitudes, and challenges our impure, selfish and proud motives. The time test proves that God is a miracle- working and faithful God. God provides after we have deleted all our own resources. God moves after all our plans fail and then He arranges a miracle and glory belongs to Him.
Abraham is the perfect Biblical example of the time test. He was 75 years old when God called him: "unto thy seed will I give this land." Abraham at this time was childless, so Abraham made his slave Eleazer his heir. But God said that Abraham would have a son, and again Abraham takes the situation into his own hands. Ishamel is born by Hagar when Abraham is 86. But finally when Abraham turns 100 years old Isaac is born, who is God's promised child. Abraham had to wait 25 years for his natural son, his true heir. Isaac was a miracle birth!
Time is not our enemy! God has a purpose for the delay. If we submit to God's time table with patience, our faith can grow and our motives can be purified. The Word God gave you will not return void or unfulfilled, instead it will give God glory!
