Deuteronomy 7:22 The LORD your God will clear away theses nations before you little by little; you will not be able to put an end to them quickly, for the wild beasts would grow too numerous for you.
The renewing of our minds will take place little by little. Pride may be one of the “beasts” that will consume us if we receive too much freedom too quickly.
I Peter 5:10 After you have suffered for a little while, the God of all grace, who called you according to His eternal glory in Christ, will Himself perfect, confirm, strenthen, and establish you.
Many times suffering precedes liberation. This may be so that God can grow our faith in Him. It may also make us grateful when the liberation does finally come. We can thank God for every victory.
