1 Corinthians 13:8: Charity (love) never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away.
Conditional love is, at best, part-time. It is inconsistent. Many seem to say to the Lord and to others: If you do this or give me that I will love you. Conditional love is an attempt to control someone, sometimes other men and sometimes even God Himself. God*s love is constant and He wants ours to be. He loved us when we were unforgiven sinners, He loves us when we are His obedient children and He loves us when we are disobedient children, when we harm ourselves and others by sinning. He always wants to forgive us. Our love for others should be like His. We should be eager to forgive.
Romans 5:8: But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us.
1 John 3:1a: Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: . . .
1 John 1:9: If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
When we sin, He does not stop loving us. We are the ones who reject His love and prevent it from blessing us. Our unconfessed, unforsaken and unforgiven sin is what keeps His love from reaching us. By our sin we create a condition that deprives us of His unconditional love.
Isaiah 59:2: But your iniquities have separated between you and your God, and your sins have hid his face from you, that he will not hear.
Jude 1:21: Keep yourselves in the love of God, looking for the mercy of our Lord Jesus Christ unto eternal life.
The way to keep ourselves in the unconditional love of God is to confess our sin and forsake it.
Proverbs 28:13: He that covereth his sins shall not prosper: but whoso confesseth and forsaketh them shall have mercy.
