This is the evidence that proves God's love for us! He demonstrates the depth of His love for us in this ultimate action. Christ died not for the good or the righteous, but for sinners who deserve wrath instead of love. This proof of God's everlasting love for us was fulfilled/completed on the cross. "Love sent my Lord to the cross of shame, Love found a way, O praise His holy Name!" (Unknown) "The Cross is an event of the past but it keeps showing the love of God." (Leon Morris)
God's love for us is agape love (unconditional, sacrificial, selfless love). It seeks the highest good for another no matter what the cost may be, as shown by Christ's sacrificial death on our behalf. God gives us His Best and Greatest Gift while we're at our worst state. Christ took the punishment that we deserve because He loves us. He paid the price/penalty that we could never pay. God loves the ungodly, the unworthy, the unlovable, the ungrateful, the undeserved. God did not wait for us to become good or to acknowledge Him before He decided to save us. Christ died for our sins even when we're still enemies of God. God loves us before we turn to Him...before we seek Him...before we love Him. His love for us does not depend on who we are or what we do. I'm so glad it doesn't because this means God's amazing love for me never changes! God is love and God is immutable!
