When God asked Noah to build the ark of safety from the destruction He was about to bring upon the earth, Noah obeyed and started building. For about 55-75 years Noah was building this ark with no flood or a raindrop in sight.
What makes this very remarkable to me is that prior to this time, Noah knew nothing about rain, never seen it, never heard about it. He stayed with God and kept building, consider the likelihood of him being mocked at, laughed at and probably reduced to being mentally sick, but he kept on till the end. God rewarded him with a covenant because of the trust he displayed in Him against all odds.
Persistence with God, following Him relentlessly in spite of what we feel, or what others may think certainly does impress God and earns one a place in His kingdom.
And Jesus said unto him, No man, having put his hand to the plough, and looking back, is fit for the kingdom of God. Luke 9:62 KJV
