Is baptism in the Spirit synonymous with conversion, or is it a subsequent experience? Working from 1 Corinthians 12:13, this article shows that baptism in the Spirit is a once-off experience synonymous to conversion whereby we are assured of our unity with Christ and His church by the Spirit, who enables us to serve one another.
Hebrews 13:20-21 should be the prayer of every believer for himself and other believers. We should pray that we may come to know God's peace, the power of Christ's resurrection, the assurance of salvation that we have in Christ, and the desire to do what is pleasing to God.
Taking hold of God's promises, using opportunities well, possessing humility, developing contentment and applying biblical wisdom are the ingredients to facing old age full of joy instead of regret.
