Gen 26:12-13 “Then Isaac sowed in that land, and reaped in the same year a hundredfold; and the Lord blessed him. 13 The man began to prosper, and continued prospering until he became very prosperous;”
Abraham was blessed by God through Faith (Gen 22). Isaac did not took the imitative to go down to Egypt which looks good during the times of famine, but obeyed God to stay in the place where God told him to live. When he obeyed God’s voice and trusted Him in Faith, he was blessed by God abundantly. He sowed in that famine stricken land itself and God gave him a hundredfold. God can bless you where you are now; same place, job, marriage, house, womb etc… Nothing is impossible for God. When we take our own initiative through our own wisdom to reach His fullness that is when we face problems.
