Jesus, the Good Shepherd, gives us "eternal life." "Yes, God so loved the world that He gave His only Son, that whoever believes in Him may not die but may have eternal life" (Jn 3:16). We all are "destined for life everlasting" (see Acts 13:48). However, we must not convict ourselves as "unworthy of everlasting life" (Acts 13:46).
When we renewed our baptismal promises three weeks ago, we chose to be "worthy of everlasting life." However, just as an unbeliever can change from rejecting everlasting life, so a believer can change and fall away from the faith (see 2 Pt 2:20ff; 2 Cor 11:3-4). We must choose to live for Jesus, and we must persevere in that decision.
You may feel confident that you have eternal life and will stay that way. You should have confidence because Jesus promised that no one will snatch you out of His hand (Jn 10:28). However, our confidence is based on His grace and not our strength. "Let anyone who thinks he is standing upright watch out lest he fall!" (1 Cor 10:12)
Today, renew your total commitment to Jesus, the Good Shepherd, our Lord, our Life, and our God. Renew your baptismal promises. Choose to live in a manner worthy of everlasting life. Live for Jesus forever.
