Christ redeemed us from the curse of the law by becoming a curse for us - for it is written, "Cursed is everyone who is hanged on a tree" (Galatians 3:13)
So many people fall into the trap that they are not good enough for God. They feel that everything they've tried has failed, so it must mean that they don't have what it takes. But the fact is, that Jesus became "not good enough" to show us that we don't have to be good enough. We'll never measure up to the standard to achieve His love on our own. It's only by HIS grace and HIS work on the Cross.
Don't allow discouragement to creep in and overwhelm you in your failures. Continue to see that Jesus' love doesn't stop because you - it continues because of you. When you realize this truth, let it compel you to live in a way that most honors Him.
